Thanks littlefish. It's just two drawings (the top one of the kitchen and the one of the taps/shower). The other two are close-ups of the first one The bottom one of the bathtub is, obviously, a photograph. Since I didn't feel like braving the miserable weather in London on Sketchcrawl day, I stayed home, started late and spent more time on less.
